Excuse my noobness. I just don't understand how to implement it to work with my code. What I'm doing is editing a name that's in a list view. When editing the name in "EditDeleteList" and get back to the previous activity (ListView) to see the name updated within the list view, nothing happens. I have to go out of the activity completely to see the change reflected. How do I get this to update? I implement an onActivityReult() method but then get this error message "java.lang.NullPointerException: Attempt to invoke interface method 'int java.util.List.size()' on a null object reference" so I removed it completely. How I could get the list view to update without getting that error message?

EditDeleteList.java
public class EditDeleteList extends AppCompatActivity {

private ImageView ivApprove;
private EditText editHashtag;
private String selectedName;

setContentView(R.layout.activity_edit_delete);
mDatabaseHelper = new DatabaseHelper(this);
editHashtag = (EditText) findViewById(R.id.editHashtag);
ivDelete = (ImageView) findViewById(R.id.ivDelete);
ivApprove = (ImageView) findViewById(R.id.ivApprove);
//get the intent extra from the ListView activity
final Intent receivedIntent = getIntent();
//get item ID passed as an extra
selectedID = receivedIntent.getIntExtra("id", -1);
//get name passed as an extra
selectedName = receivedIntent.getStringExtra("name");
//set text field to selected item text
editHashtag.setText(selectedName);
ivApprove.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String item = editHashtag.getText().toString();
if (!item.equals(null)) {
mDatabaseHelper.updateName(item, selectedID, selectedName);
} else {
toastMessage("you must enter a #hashtag");
}
finish();
}
});
}
private void toastMessage(String message) {
Toast.makeText(this, message, Toast.LENGTH_SHORT).show();
}
}
In the EditDeleteList.java I have an onClickListener that saves the changes and goes back to the previous activity by using finish();
ivApprove.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String item = editHashtag.getText().toString();
if (!item.equals(null)) {
mDatabaseHelper.updateName(item, selectedID, selectedName);
} else {
toastMessage("you must enter a #hashtag");
}
finish();
}
});
Notify the adapter in some part of the activity lifecycle.
OnCreate() should not run when you go back (this is the reason you have to completely recreate the activity to see the list updated) so you should use OnRestart/OnStart/OnResume to notify the adapter to check for new items.

This is probably a dumb question but I'm very new to coding so please bear with me.
I am trying to make audiofiles play when a button is pressed and a song is selected in the spinner. But the number doesnt seem to be updating and I only get the same song played.
private void Onclick() {
final int[] songlist ={
R.raw.salsa,
R.raw.fantasy,
};
mp = MediaPlayer.create(this, songlist[spinner.getSelectedItemPosition()]);
mp.setLooping(true);
play_btn.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
mp.start();}
});}
Why doesnt this work?
EDIT: onCreate method
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
play_btn = (ImageButton) findViewById(R.id.play_btn);
spinner = (Spinner) findViewById(R.id.song_spinner);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
R.array.songs_array, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
Onclick();
}
You can go with this:
add a class property like:
final int[] songlist ={
R.raw.salsa,
R.raw.fantasy,
};
int selectedSong; //default to 0
Then in your class, you can add a listener on spinner value change events with this:
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
selectedSong = position;
}
#Override
public void onNothingSelected(AdapterView<?> parentView) {}
});
And now in the button onClick, you can go with this code:
play_btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mp = MediaPlayer.create(MainActivity.this, songlist[selectedSong]);
mp.setLooping(true);
mp.start();
}
});
To make this work all you have to do is initialise the media-player object every time when you click on the button pressed.
play_btn.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
// in your code it is initialised with the first selected object
mp = MediaPlayer.create(this, songlist[spinner.getSelectedItemPosition()]);
mp.setLooping(true);
mp.start();}
})};
So, I've been struggling on this for a while and have searched on here for hours without finding anything that really helped. I have a custom class Streak. When the user creates a new Streak in my Main Activity, I want for that streak to be added to a list of total streaks, which I would then access from an AllStreaks activity. I have tried using Gson, but received errors. What I have below is working for the time being, but since my global variable has to be declared as new. I don't really want to use a MySQL database as this info needs to be quickly editable and I don't want to have to constantly connect to that to potentially change just one detail.
Sorry if my code is a mess or this makes no sense, I'm coming to realize I'm really shitty at programming anyway.

you cannot pass object directly.you have to parcelable or serialize it. but in parecelable is part of android where serialzation is part of java so i suggest you to use parcelable.
you can make model class to parcelable from this link if you dont want to code for parcelabel.
parcelable creator
you can achieve like this.
class Car implements Parcelable {
public int regId;
public String brand;
public String color;
public Car(Parcel source) {
regId = source.getInt();
brand = source.getString();
color = source.getString();
}
public Car(int regId, String brand, String color) {
this.regId = regId;
this.brand = brand;
this.color = color;
}
public int describeContents() {
return this.hashCode();
}
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(regId);
dest.writeString(brand);
dest.writeString(color);
}
public static final Parcelable.Creator CREATOR
= new Parcelable.Creator() {
public Car createFromParcel(Parcel in) {
return new Car(in);
}
public Car[] newArray(int size) {
return new Car[size];
}
};}
And you can pass it like below.
ArrayList carList = new ArrayList();
carList.add(new Car('1','Honda','Black');
carList.add(new Car('2','Toyota','Blue');
carList.add(new Car('3','Suzuki','Green');
Intent i = new Intent(getApplicationContext(), CarDetailActivity.class);
i.putParcelableArrayListExtra("cars", carList);
this.startActivity(i);
you can get it like below:
Intent i = this.getIntent();
ArrayList<Car> carList = (ArrayList<Car>)i.getParcelableArrayListExtra("cars");`
You need to use Parcelable or Serializable interface.
and the pass it with intent
Intent mIntent = new Intent(context, ResultActivity.class);
mIntent.putParcelableArrayListExtra("list", mArraylist);
startActivity(mIntent);
fetch it in ResultActivity
Bundle bundle = getIntent().getExtras();
mArraylist1 = bundle.getParcelableArrayList("list");
Check this thread for reference
Do this on your Streak class and try,
Streak implements Parcelable
Since your modal class has not serialized, it may not able to pass via bundle. You can do that by implementing the Parcelable interface.
Parcelable is an Android specific interface where you implement the
serialization yourself. It was created to be far more efficient that
Serializable, and to get around some problems with the default Java
serialization scheme.
Serializable is a standard Java interface. You simply mark a class
Serializable by implementing the interface, and Java will
automatically serialize it in certain situations.

How can i start a new activity with a button when i select from a spinner?
my code tho.. i've searched a lot but nothing works, hope something happens here :)
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ImageButton button = (ImageButton) findViewById(R.id.imgbtnarroceros);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(MainActivity.this, Main2Activity.class);
startActivity(intent);
}
});
Spinner spinner;
spinner= (Spinner) findViewById(R.id.spinner) ;
ArrayAdapter adapter = ArrayAdapter.createFromResource(this, R.array.itinerary, android.R.layout.simple_spinner_item) ;
spinner.setAdapter(adapter);
From my understanding, you want to open an activity which has a button when you select an item from the spinner. Please correct me if my understanding is wrong.
setOnItemSelectedListener to your spinner and handle the item select event.
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
switch(position){
case 0:
//start activity on selection of any item you want, here I am assuming first item.
Intent intent = new Intent(YourCurrentActivity.this, ActivityWithButton.class);
startActivity(intent);
break;
}
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
I have a list of Clickable TextViews that are relatively doing the same thing. You click on it and it goes to that activity. Settings goes to the settings activity. About to the about and so forth. Is there an easier way to declare and set up these clickable TextViews besides this repetitious code?
TextView create,
edit,
settings,
about;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_navigation);
create = (TextView) findViewById(R.id.create);
create.setTextColor(Color.parseColor("#000000"));
edit = (TextView) findViewById(R.id.edit);
edit.setTextColor(Color.parseColor("#000000"));
settings = (TextView) findViewById(R.id.settings);
settings.setTextColor(Color.parseColor("#000000"));
about = (TextView) findViewById(R.id.about);
about.setTextColor(Color.parseColor("#000000"));
create.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
}
});
edit.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v){
}
});
settings.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v){
}
});
about.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v){
}
});
If you have a small set of items you can take following approach:
public class MyActivity extends Activity implements AdapterView.OnItemClickListener {
private ArrayAdapter<Item> mAdapter;
private static enum Item {Create,Edit,Settings,About}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//-- can set up from external layout also--
ListView list = new ListView(this);
setContentView(list);
list.setOnItemClickListener(this);
mAdapter = new ArrayAdapter<Item>(this,android.R.layout.simple_list_item_1,Item.values());
list.setAdapter(mAdapter);
}
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
switch (mAdapter.getItem(i)){
case Create:
//--do stuff--
break;
case Edit:
//--do stuff--
break;
case Settings:
//--do stuff--
break;
case About:
//--do stuff--
break;
}
}
}
You can implement the View.OnClickListener .
public class YOURACTIVITY extends Activity implements OnClickListener
And in the onCreate()-
yourTextview.setOnClickListener(this);
and then
#Override
public void onClick(View v) {
// Based on the view , set the action
}
